A rock is thrown vertically upward from the ground with an initial speed 15m/s.

a. how high does go?
b. how much time is required for the rock to reach its maximum height?
c. what is the rock's height at t=2.00s?

  • physics -

    At the top, final veloctiy is zero.
    Vf=Vi-g*t to get time

    h= Vi*t-1/2 g t^2 to get height.
